Cost, application, dosage, and additional details regarding Vyvgart treatment
In the world of neurological treatments, a significant development has emerged with the introduction of a new formulation of Vyvgart. This drug, used to treat generalized myasthenia gravis (gMG), is now available as a subcutaneous (SC) injection, offering patients a more convenient option.
The original formulation of Vyvgart, known as Vyvgart IV, is an intravenous (IV) infusion administered over approximately an hour. It is typically dosed at 10 mg/kg once weekly for four weeks per cycle. This drug is indicated for adult gMG patients who are anti-acetylcholine receptor (AChR) antibody positive.
The new formulation, Vyvgart Hytrulo, is a game-changer. Co-formulated with the enzyme hyaluronidase, it allows for rapid SC administration over 20-30 seconds. This subcutaneous injection contains efgartigimod alfa 1,008 mg plus 11,200 units hyaluronidase. Approved in June 2023, Vyvgart Hytrulo is not only indicated for the same gMG population as Vyvgart but also for chronic inflammatory demyelinating polyneuropathy (CIDP).
The convenience of Vyvgart Hytrulo extends to self-administration. The prefilled syringe, equipped with ENHANZE technology by Halozyme, enables patients to administer the drug themselves. This alternative to the IV infusion offers a significant improvement in ease and flexibility for those managing their condition.
Comparatively, the original Vyvgart is prescribed by a doctor and is not a controlled substance. The dosage of Vyvgart depends on factors such as the severity of the condition and body weight. It is essential to note that Vyvgart may interact with intravenous immunoglobulin (IVIg), monoclonal antibodies such as rituximab and belimumab, and live vaccines such as the nasal spray flu vaccine and the measles, mumps, and rubella (MMR) vaccine.
Symptoms of a mild allergic reaction to Vyvgart can include a skin rash, itchiness, or flushing. A more severe allergic reaction to Vyvgart is rare but possible, with symptoms such as swelling under the skin, swelling of the tongue, mouth, or throat, and trouble breathing. Details about these severe allergic reaction side effects can be found below under "Allergic reaction."
As with any medication, it is crucial to discuss any medical conditions or other factors affecting your health with your doctor before taking Vyvgart. This includes active infections, previous allergic or infusion reactions to Vyvgart or similar drugs, pregnancy, breastfeeding, and more.
In summary, the introduction of Vyvgart Hytrulo provides a new, more convenient option for those living with generalized myasthenia gravis and CIDP. As always, it is essential to consult with a healthcare professional for personalised advice and guidance.
